REGISTERING AND ANNUNCIATING DEVICE FOR CARS.

SPECIFICATION forming part of Letters Patent No. 744,704, dated November 24, 1903.

Application filed July 15, 1903. serial No. 165.707. (No model.)

To (11 whom it may concern/.-

Be it known that I, AMEEN GAIRGE ABI- ZAID, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Registering and Annunciating Devices for Cars, of which the following is a specification.

My invention relates to improvements in annunciating devices by means of which the motorman is enabled to announce the different cross-streets as theyare being approached and the object of the invention is to simplify and improve the construction over the existing prior state of the art.

With these ends inview the invention consists in the novel construction and arrangement of parts, as will be hereinafter more in detail described, and particularly pointed out in-the claim.

I have fully and clearly illustrated my invention in the accompanying drawings, in which- Figure l is a side elevation of the front portion of a car with my invention applied thereto. Fig. 2 is an elevation of a registering device. Fig. 3 is a sectional view of the registering mechanism, the top being removed; and Fig. 4 is a side sectional elevation of the same.

Like letters of reference denote corresponding parts on the several figures.

A designates a side portion of the front of a car provided with a hollow partition 0., secured to the top and floor of the car. B designates a sheave secured to the floor of said car, around which a rope?) is passed from a push-button mechanism to the bell and drum registering mechanism hereinafter explained.

0 designates a lever pivotally secured to the lower end of a push-button rod 0, having a push-button c at its opposite end, the rod being projected through theplatform of the car. ,The forward end of this lever is secured on hangers 0 secured to the under side of The rope I) to a hanger 01, over which sheave the cord passes, connecting the lower end of a pawllever E with a bell attachment F. This lever is pivoted on standard I and projects through an orifice in a bracket G, to which the bell H is secured.

K designates a short tube having one end secured to the side of the casing, in which a end is mortised out, as at Z, and in this mor-.

tise is located at right angles to the spring is another small spring, is. Through these springs, in conjunction with the pull-rope b,

motion is communicated to a rotatable drum L by means of the pawl formed upon the upw per end of thelever E meshing with the teeth of a ratchet-wheel M, secured to one end of a shaft m, a spring m being secured to the inner side ofthe casing J, the free end of which engages with the ratchet-teeth of the ratchet-wheel M. A bowed spring N is secured to the side of the casing adjacent to the drum, upon which the latter bears. The object of the spring N is to regulate the movement and prevent too great a momentum of the cylinder in, its revolution when forced around by the pawl-lever. Upon the periphery of the drum are indicated the different streets which the car crosses, the action of the pawl upon the ratchet-wheel advancing the drum and displaying the particular crossstreet which is being approached.

. Having thus described my invention, what I claim as'new, and desire to secure by Letters Patent, is

A push-button device for passenger-cars comprising a lever C, journaled in hearings in the front of the car, a push-button rod passed through the platform of the car and having its lower end secured to said lever, a

push-button secured to its opposite end, a.

upper end of the lever bears, a spring in the upper end of the pawl-lever, an indicatiugdrum journaled in hearings in the casing upon which the streets are indicated, a

5 'ratchetwheel secured to the drum-shaft in which the end of the pawl -1ever takes, a spring-dog secured to the casing which takes in the teeth of the ratchet-wheel, and a spring secured to the side of the casing, and located IO adjacent to the drum upon which the drum bears, all arranged and operated as herein shown and described.

In testimony whereof I have signed my name to this specification in presence of two witnesses. 15

AMEEN GAIRGE ABIZAID.
